"NVIDIA owns the high end graphics market. For the past six months, there has been no challenge to the performance leadership of the GeForce 8800 GTX. Since the emergence of Windows Vista, NVIDIA hardware has been the only platform to support DX10. And now, before AMD has come to market with any competing solution whatsoever, NVIDIA is releasing a refresh of its top of the line part.
The GeForce 8800 Ultra debuting today doesn't have any new features over the original 8800 GTX. The GPU is still manufactured using a 90nm process, and the transistor count hasn't changed. This is different silicon (A3 revision), but the GPU has only really been tweaked rather than redesigned.
Not only will NVIDIA's new part offer higher performance than the current leader, but it will introduce a new price point in the consumer graphics market moving well beyond the current $600 - $650 set by the 8800 GTX, skipping over the $700 mark to a new high of $830. That's right, this new high end graphics card will be priced $230 higher than the current performance leader. With such a big leap in price, we had hoped to see a proportional leap in performance. Unfortunately, for the 38% increase in price, we only get a ~10% increase in core and shader clock speeds, and a 20% increase in memory clock."
